Анализ диффузионных напряжений в плоской мембране реактора для производства синтетического газа

Abstract

Diffusion of oxygen vacancies in a planar membrane of reactor for production of synthesis gas has been considered. A planar membrane has been modeled as the thin round plate under conditions of the generalized plane stress. Analytical solution with determination of oxygen vacancies concentration and diffusion induced stresses has been obtained taking into account chemical surface exchange. Numerical example with the two types of the boundary conditions has been considered
